Four ECM ubiquitous protein components, each of which comprises multiple, distinct, repeating domains, are found in basal laminae. Given below are a list of some extracellular matrix (ECM) proteins in column A and their characteristics in column B.

Column A

Column B

a. Type IV collagen

i. a large multidomain proteoglycan that binds to and cross-links many ECM components and cell-surface molecules.

b. Laminins

ii. a rodlike molecule that cross-links type IV collagen, perlecan, and laminin, which

helps incorporate other components into the ECM and also stabilizes basal laminae.

c. Perlecan

iii. a family of multi-adhesive, cross-shaped proteins that form a fibrous two-dimensional network with type IV collagen and that also bind to integrins and other adhesion

receptors.

d. Nidogen

iv. trimeric molecules with both rodlike

and globular domains that form a two-dimensional network.

Which one of the following is the most appropriate match?

  3. a-iv, b-iii, c-i, d-ii

Following statements are regarding to model for reassembly of the nuclear envelope during telophase. 
A. Extensions of the endoplasmic reticulum (ER) associate with each decondensing chromosome and then fuse with one another, forming a double membrane around the chromosome. 
B. Dephosphorylated nuclear pore subcomplexes reassemble into nuclear pores, forming individual mini-nuclei called karyomeres. 
C. The enclosed chromosome further decondenses, and subsequent fusion of the nuclear envelopes of all the karyomeres at each spindle pole forms a single nucleus containing a full set of chromosomes.
D. Phosphorylated nuclear pore subcomplexes reassemble into nuclear pores, forming individual mini-nuclei called karyomeres.
